– A single transporter protein in the cytoplasmic membrane<br />
– Determines the substrate specificity and resistance<br />
Three component (tripartite) systems<br />
– Exclusively in Gram negative species (GNB)<br />
♦ A transporter protein<br />
♦ A periplasmic adaptor lipoprotein<br />
♦ A outer membrane channel protein<br />
